Take a tour of the installation
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.

Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
An HVAC installation project in the heart of an urban Montreal condo
At AirGreen , we were recently approached for a project in a condo located in Rosemont–La Petite-Patrie , a vibrant neighborhood of Montreal where indoor comfort and energy efficiency are priorities for residents. The installation involved a Zephyr wall-mounted heat pump , a choice that combines performance, discreet design, and a perfect fit for the realities of urban housing.
The indoor unit was positioned above a door leading to the balcony, ensuring optimal distribution of fresh and warm air into the main room while respecting the space constraints specific to condos. This type of configuration requires careful planning and precise execution, two aspects that define the AirGreen method.
The advantages of the Zephyr wall-mounted heat pump
Over the years, the Zephyr brand has established itself as a reliable and affordable option for homeowners in Greater Montreal. Its distinctive features include:
-
Remarkable energy efficiency , reducing electricity consumption year-round.
-
Stable performance down to -25°C , ensuring continuous comfort, even during harsh winters.
-
Quiet operation , ideal for condos and apartments where acoustics are an important issue.
-
A clean and modern design , integrating perfectly into contemporary environments like those of Rosemont.
Challenges encountered and solutions applied
Every HVAC installation project has its own unique challenges. In this case, our team faced several challenges:
-
Space constraint : The unit had to be installed above a door frame, below a ceiling light fixture. We adjusted the wall mounts to meet safety clearances and ensure optimal airflow.
-
Refrigerant pipe route : a discreet hole was made behind the unit, then the pipes were carefully camouflaged using white capping to preserve the aesthetics of the room.
-
Drainage management : the installation was designed using gravity, taking advantage of the proximity to the exterior to avoid the addition of a condensate pump.
Thanks to these technical choices, we have delivered an installation that combines reliability and elegance.
Comfort and savings for occupants
From the moment it was turned on, the occupants noticed a significant improvement in thermal comfort. The Zephyr unit not only efficiently cools hot summer days, but also heats the main room during the winter, reducing dependence on traditional heating systems.
In addition, the device is eligible for certain Quebec government subsidies , notably under the LogisVert and Rénoclimat programs, thanks to its energy performance. AirGreen support always includes complete assistance in these procedures, so that our customers maximize their savings.
A typical installation in Montreal's urban environment

-
Provide adequate drainage : gravity drainage is often simpler and more durable.
-
Work with a certified installer : only a qualified team can guarantee a safe and efficient installation.

The big day, step by step
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

What would it look like at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.

Your own project, step by step
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
